accel/rocket: Fix prep_bo ioctl leaking positive return from dma_resv_wait_timeout()
dma_resv_wait_timeout() returns a positive 'remaining jiffies' value
on success, 0 on timeout, and -errno on failure.
rocket_ioctl_prep_bo() returns this 'long' result from an int-typed
ioctl handler, so positive values reach userspace as bogus errors.
Explicitly set ret to 0 on the success path.
